I was under the impression that the explicit aim of the ADS-B directive is to phase out SSR, which would would save a massive amount of money.

How does the FAA think this is going to work after 2020 when air traffic control will run off of ADS-B positional telemetry from aircraft. It seems a GPS shutdown like this would basically shut down IFR flying and airport terminal control s

If the alternative is sitting in stop and go traffic, it's not obvious to me that one is worse than the other...

Falling asleep like that is likely a symptom of severe sleep deprivation, not a personal characteristic.

What do you mean? Daylight is very close to a blackbody.

I'm not disputing the fact that there is a difference. But whether it's perceptible depends on where in the spectrum the differences are in relation to what you are looking at and the response curves of your cones. Not to mentio

by lutorm 10y ago
The problem is that comparing a spectrum isn't actually meaningful. I really don't care about the spectral shape of the light if it's not perceptible to me. You want some sort of quantitative estimate of what you care about

You don't want "natural" lighting if you want it to look like an incandescent. "Natural", ie "day" light is very blue. You specifically want a non -natural, warm color temperature.

Depends strongly on the situation. It's true that where heating would be used, if mounted in such a way that all that heat is available (ie, not recessed into a ceiling fixture), the 97% is useful. (But not necessarily maximally eff

Indeed it is, but that doesn't mean anything illuminated by a blackbody "match the hue of objects seen in natural daylight." CRI has much more to do with the ability to discriminate colors. The absolute hue is a strong functi

I was going to say the same thing. People are confusing "continuous spectrum" with "solar spectrum". Try comparing a "daylight" bulb with a normal incandescent. The color temperature of the sun is ~5500K. The d

If it's a background check, it's a background check. Otherwise it's "mandatory registration in the government's database", not a background check. There's a difference between retaining the fingerprints of

The second stage has a smaller ballistic coefficient than the first one, though. Their cross-sectional areas are the same, but an empty second stage has much less mass. If it could survive entry (and that's a big if), it's termina

This is a good point. Remember that the early "sea landing" experiments ended with the stage breaking up just from falling over into the water.

I'd also advise you to remember that SpaceX isn't taking kindly to employees passing out internal information.

It's not accurate; they don't build all parts, just most of them.

I think it also depends a lot on where in the company you are. If you are directly responsible for something needed to launch, there's naturally going to be a lot of pressure. If you are more removed from the direct launch operations,

Sounds like my Swedish taxes. All I have to do, if I agree with the information already on there, is sign it (electronically, of course.)

After moving to Hawaii, I've discovered that IKEA products are largely not appropriate for tropical climates -- all the fiberboard stuff has gotten severe mold infestations. In CA, I loved going to IKEA to stock up on some swedish food

This is absolutely not the case, angle of attack is not zero, but moreover most of the orbital insertion is exo-atmospheric and you can burn in whatever attitude you want. The factor determining the accuracy of the apogee of your orbit is h

ITAR allows greencard holders, so not everyone's an American citizen.

I don't understand how a link could ever be judged to infringe copyright. No copy is made, any more than if I tell my friends, in person, to go and check out the cool, copyright-infringing photo that one of us have.

What is the point of taxing an individual, given that they must also disburse their income eventually?

nobody disputes that waste and fraud are bad and should be stopped. But the problem is not nearly as widespread as generally believed - and that is the problem, because it elevates an minor issue to an outsized status at the expense of oth

When you pick up a piece of a company, you pick up assets AND liabilities. I'm not sure how it could work any other way. If a "lifetime warranty" can define lifetime as "until we don't want it to live any longer&quo

The phenomenom you're talking about is called "interrupted checklist" in aviation. Humans are actually quite good at following memorized lists unless they get interrupted mid-task. When this happens, the risk of a mistake g

It's also fair to point out that this is not a universal system. I'm pretty sure Italy by default treats aircraft accidents as crime scenes where responsibility is to be assigned.

The FAA has also recently said that it's going to change its focus on enforcement through punishment and aim for a reduction of violations through education and training.

They conveniently omitted Hawaii from that map. Solar here is already cheaper than the grid, even after the very high installation costs and even if you go totally off-grid.
